Explain how Jinja template tool works in your app. I explained how this pulls data and renders.

Example
```
{% for lot in lots %}
 <li>{{ lot.name }} — {{ lot.spots }}</li>
{% else %}
 No lots
{% endfor %}
```

Advice: Please learn how to add/delete columns in db safely. Also learn how to pull and display the modifcations to final html. It's not a GPT's work. You only know your app, so learn to plug codes wherever necessary. Be respectful.....
